An "n" on the display is usually the start of a "no" code, like no FL (no flame), no AC, no dc, or no CO. Watch the display for the full code, then look it up on our Norcold error codes page. Before you buy another board, check that you have a solid 12V DC at the board. Low voltage causes a lot of these codes. Then turn the fridge off, pull the 12V fuse for a minute, and restore it to reset. If the code comes right back, the code tells you where to look. If you'd like help working through it, our tech support service can walk you through it. If you have any questions, just reach out at info@rvfridgeguys.com or call us at 800-712-8822.
